Well, i noticed in the strat map something that seemed like a small geographical mistake. Angleton is a small region placed in the "angle" just over the point where the river Hoardwell and Loudwater mets, and you put it in the "angle" were the same Hoardwell mets with Glanduin, some miles southwest from where it really were.
For more concrete references:
The River Hoardwell (or Mitheithel in Elven), rose in the northern Misty Mountains a hundred miles north of Rivendell, and runs southward until it met Glanduin (just above the abandoned fortress of Tharbard) and forms the river Greyflood (or Gwathlo)
The River Loudwater (or Bruinen in Elven), rose in the western Misty Mountains and flowed southwestwards past Rivendell. This is the River were Glorfindel (or Arwen in the Movie) helped by Elrond´s magic stops the Ringwraiths, and it is an tributary of Hoardwell.
Finally, the river Glanduin begins in the Misty Mountains south of Khazad-Dum, flowing west-north-west marking the limit of the old kingdom of Eregion (of which Rivendell is the last remain), and then south-west towards the Hoardwell which it met in the marshes known as Swanfleet (or Nin-In-Eiliph) north-east of Tharbard. From there on Glanduin and Hoardwell merges into the Greyflood
This is not overly important and i thought that you made this on purpose to make Dunland a more huge territory, but anyways i wanted to ask.
